Application led February 21, 1913. Serial No. 749,936.

To all whom 'it may concern:

Be it known that I, GEORGE ELMER GRAY, citizen of the `United States,residing at Des Moines, Iowa, have invented certain new and usefulImprovements in Pumpin Means4 for Massage Devices, of which thefollowing is a specification.

My present invention relates to improvements in massage apparatus of thetype in which water from a faucet is used to secure the necessarysuction or partial vacuum.

The invention has among others for its be readily applied to and removedfrom any ordinary faucet, which will secure a maximum amount of suction,and give an eiicient massage action; and whichv will be of simple andeconomical construction.

With these and other objects-in view, the invention includes the novel4features of construction and arrangement and combination of partshereinafter described and particularly defined by the 4appended claim.

In the drawing Figure 1` is a central longitudinal section of myimproved apparatus; Fig. 2 is a section on line 2 2 of Fig. 1; Fig. 3 isa section .on line 3--3 of Fig. 1; and Fig. 4 is a detail view.

Referring by reference characters to this drawing, the numeral 1designates the outer shell of the suction generator of myap aratus,which may be formed of any suitah material', preferabl by casting. It isof substantially cylin rical shape, as shown, and provided with anoverturned u per edge 2 forming a downwardly extending annular flange.This flange is adapted to engage a special coupling or. connectingwasher 3 which comprises-a body portion 3 of .tapered or truncated coneshape adapted to frictionally engage lthe nozzles of faucetsof varioussizes. At its upper-.end the body has a cylindrical portion `3 providedat its lower edge with an outwardly extended and upwardly elongatedannular flange 3 adapted to rest in the recess formed beneath theoverturned upper edge 2 of the body 2 and the internal annular shoulder.The upper edge b of the washer is preferably substantially flush withthe up er edge of the body 2. The washer is furt er rovided with atransverse rib c on one 'si e.

The 'shell l of the generator is provided, a short distance below thelower end of the washer, with a horizontal partition 4, which has acentral depending injector nozzle 4 lev arranged axially of the body ofthe washer. Below the partition 4 is a' second partition 5 having adownwardly tapered portion 5a terminating in a depending tubular portion5b axially in line with the injector nozzle 4. Beneath the lower end ofthe tubular por- Vtion5b and spaced therefrom is placed a deiiectingdisk 6 supported by the portions 6a. The water flowing down through theinjector nozzle 4a into the cone 5 and tube or 'leg 5b causes a suctionin the space or chamber between partitions 4 and 5, and

as this chamber is in communication with applicator 8 through nipple 9and hose 10, the suction on vthe applicator is produced. The ldwer edgeof the shell lis curved inwardly and upwardly, as indicated at 7, so asto provide an annular trough with its inner edge beneath the outer edgeof thev disk 6.

The portion 4'a is preferably tapered,ia s` shown, and provided with abeveled lower edge, and this, in connection with the ta-l pered wall 5e,produces an efiicient suction,

whilethis is maintained and assisted bythe distributer 6, which throwsthe water outward from the lower end of the leg or tube ping into thechannelfat the bottom, it will tend'to be thrown up by the annularcurved wall against thebottom ofthe disk 6.

The construction of the suction devlce which I have hereinbeforedescribed I have to being formed by casting in one.integral whole, theonly separate parts being the 1 -washer and hose and applicator.Furthermore, my particular construction of Washer not only adapts itselfto various sizes of faucets, but also effects secure connection with thefaucet, as excessive pressure within the chamber surrounding the conicalportion of the faucet only tends to cause the washer to grip the faucetnozzle more tightly.

' Sometimes a faucet may be somewhat irregular in shape with the resultthat when the washer is applied thereto the water ,will lspurt upbetween the washer and faucet on account of such irregularity. Thisthepres-y ence of the lip g l Having thus described my invention what 0will prevent.

In testimony whereof, I affix my signa ture in presence of twowitnesses. GEORGE ELMER GRAY.
